1.In class, students learned that a cart will move when a force of 50 N or greater is applied. A student pushed on the cart with a force of 10 N. The cart did not move. Why not? 2. Student A pushed on the cart with a force of 500 N. Student B pushed on the other side of the cart. The cart did not move. How much force did student B apply? Explain how you know.

3. 3. Student A pushed on the cart with a force of 400 N. Student C pushed on the other side of the cart. The cart rolled to the left. Did student C apply more, less, or the same force as student A? Explain how you know.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
